or wrnonnsrnn, MASSACHUSETTS HEEL BREASTING AND "PBESSING MACHINE Application filed January 29, 1929. Serial No. 335,952.

This invention relates to means for producing a spring-heeled shoe bottom which includes a full length sole and a heel superimposed on the heel portion of the sole,.said sole and heel being usually of crepe-rubber, The

heel is adhesively united to the heel end of the sole and is beveled at its breast end to provide a face against which a transverse portion ofthe soleispressed and adhesively united to s form the inclined breast of a spring heel,

I whereof the heel end of the sole forms the tread.

The invention is embodied ina breasting and pressing machine, adapted to act on an incomplete bottom, the members of which have been united vto form the tread without being united to form the inclined breast, the machine being organized to firmly press together the heel and the heel :end of the sole,

verse portion {of :the sole and the inclined breast of the heel, and thereby complete the bottom, so that it isattachable to the superstructure of a shoe.

Figure 13 is a section on'line 13-13 of Figure 10. The same reference characters indicate the same parts in all of thefigures.

v The frame of the machine includes a fixed base 15, and a standard 16, upstanding therefrom, andprovided with bearings 17 in which a power-driven crank-shaft 18 is journaled.

The shaft is driven by well known mecha nism including an automatic stop motion, whereby the movement of the shaft is stopped after each complete rotation thereof. 7 I v A carrier 19, engaged with vertical guides 20 (Figure is connected by a pitman 21 with the crank-shaft and reciprocated in a verticalpath.

Unyieldingly supported by the base '15 is 7 a pressing bed 22, formed to support the heel member 23 and the sole member 24:, oftheincomplete shoe bottom shown by Figure l. Said members are formed from crepe-rubber, the heel member having a beveled or inclined end face 25. The heel end of the sole member is adhesively united to the heel member to produce the assembly or incomplete bottom shown by Figure 1, before the sameis presented to, the machine, the adhesive union 5 being preferably caused by first applying a solvent, such as a benzol solution, to the surfaces to be united, thereby rendering said surfaces adhesive, and then superimposing one surface on the other.

The heel is deposited on a raised portion i 22 of the bed 22, as shown by Figure 11, the forepart of the sole member resting on the bed. The carrier 19 is provided with pressing members including a platen member 26, adapted to press the heel end of the sole against the bed-supported heel, to cause a closer union of the adhesive faces to each other, and a block-shaped member 27, having a beveled acting face 28, adapted to press a transverse portion of'the sole against the beveled face 25 of the heel, as indicated by Figures 2and 12, and thereby form the exter nal face of a spring-heel breast, the said transverse portion of the sole, and the heel face 25, having been previously rendered adhesive, so that the bottom is completed, so far as the heel end thereof is concerned.

It is customary to cement a trade-mark or name label 29 to the exposed shank portion of the sole, the label being usually a disk of thin soft vulcanized rubber which is cemented to the sole when the bottom is in the incomplete condition shown by Figure 1, the label being pressed lightly on the sole by an operator. To cause a closer union between the label and the sole, I provide the, carrier 19 with a labehpressing means including a member 30,

which exerts pressure on the label,as indicated by Figure 12 during the above described pressing and breasting operation. The member 30 is in close proximity to the breasting member, and its acting face is substantially flush with the lower end of the inclined breasting face 28. The raised portion 22 of the pressing bed supports the heel above the portion-of the bed which supports the sole, so

that the label presser 30 is adapted to depress the label-supporting portion of the sole while acting on the label. When the pressure is removed, the depressed portion of the sole springs to the position shown by Figure 2. The pressing bed 22 is vertically adjustable relative to the base 15, to enable the pressing members and bed to conform to the thickness of a sole and heel supported by the bed, the machine comprising adjusting means adapted to positively support the bed in any position to which it may be vertically adjuste I prefer to embody said adjusting means in a bed-supporting wedge composed, in this instance, of two wedge-shaped members 31, and a neck 32 (Figure 5), said wedge being slidable on the base 15, an internally threaded ear 33 fixed to the base, an adjusting rod 34, journaled to rotate loosely in the neck 32, and having a threaded portion engaged with the internal thread of the ear 33, and a horizontal table 35 movably supported by the wedge members, and having grooves 36 with inclined inner faces 37, bearing on the inclined upper faces of the wedge members. The bed is supported by the table and the table and bed may be raised or lowered together by endwise movements of the wedge members caused by rotation of the rod 34, which is provided with an operating handle 38. The table 35 may be acted on by springs 39, to hold the groove faces 37 in close contactwith the wedge members 31, said springs being interposed between the table and heads 40 onvertical studs 41, fixed to the base 15 and passing through orifices in the table.

.ure 7) being provided to 410 on the table'35 to permit a horizontal tion to receive the assembled sole and heel,

and'an inward movement to locate the sole and heel in position to be actedon by the pressing members, a stop member 42 (Figlimit the inward sliding movement.

v To correctly position the heel and sole on the bed 22, I provide the latter with a positioning gage 43, provided with a recessed abutment face 44, formed to bear on portions of the curved margin of the heel and arranged to locate the heel and sole in predetermined positions on the bed. The gage is horizontally adjustable onthe bed to conformthe abutment face, to heels of different areas, means-being provided for adjusting the gage and positively holding it in any position to which it may be adjusted. In this instance I have embodied said means in an ear 45, fixed to the gage and provided with atapped' orifice, andfarod 46 journaled at one end to rotate in an ear 47 on the outer end of the bed 22, and provided with a handle 48, whereby itmay be turned to adjust the gage. i The breasting member 27 is preferably adjust-ably connected with the ca'rrier19,;so that its inclined acting face 28 may be slightly raised or lowered. To this end, the member 27 is adapted to slide vertically relative to the carrier and is provided with a' tapped socket 49 (Figure 10) engaged with an adjusting screw 50, which is journaled torotate without endwise movement in the carrier. I 7

The presser or platen 26' is horizontally movable on guides 51, on the carrier, as indicated by Figure 13, and is pressed yieldingly by a spring 52 against the-acting face 28 of thebreasting pressen, f The label presse'r 30 is movable in a hollow casing53, fixed to the carrier and is yieldingly pressed downward by a spring 54 in the casing, so that its pressure on the label 29 will notbe too positive. i
